[EN]The effect of three natural diets (sardine, crab and squid), used for feeding Octopus vulgaris broodstocks was studied in the spawning quality and total amino acid composition of eggs and hatchling. Multivariate techniques were used to reveal groups based on the diet and to relate the amino acid profile of the spawning with the parameters of quality. The analysis allowed us to discriminate the composition of eggs based on the total amino acid contents; however, hatchling showed a homogeneous amino acid composition between the three groups. Pearson's correlation analysis found that eggs composition showed a greater degree of relation to the spawn quality parameters than hatchling.
[ES] Optimizar la dieta de los reproductores en peces ha demostrado ser una forma efectiva de mejorar la calidad de la puesta (Watanabe y Vasallo-Agius, 2003). En el caso del pulpo común, Quintana et al., (2007) han puesto de manifiesto la influencia de la dieta de los reproductores sobre la composición lipídica de huevos y paralarvas y su relación con la calidad de puesta. Dado la importancia de la proteína en el metabolismo de cefalópodos (Villanueva y Norman 2008), en el presente estudio se pretende completar esta línea analizando la influencia de la dieta de los reproductores en la composición de aminoácidos (AA) de huevos y paralarvas y sus efectos sobre la calidad de puesta.
